Let’s solve the math problem shown in the “Number & Operations in Base 10” worksheet.

We are asked to find:
382 + 421 = ?

Step-by-step:

First, line up the numbers by place value (ones, tens, hundreds):

```
382
+ 421
------
```

Now add column by column, starting from the right (ones place):

Ones place:
2 + 1 = 3

Tens place:
8 + 2 = 10 → Write down 0, carry over 1 to the hundreds place.

Hundreds place:
3 + 4 = 7, plus the carried-over 1 = 8

So putting it all together:

```
382
+ 421
------
803
```

Double-checking:
- 300 + 400 = 700
- 80 + 20 = 100 → so now we have 800
- 2 + 1 = 3 → total is 803 ✔

Final Answer:
803
